1.1 Introduction to Information Center
The information center is an indispensable part of the switch. It serves as an
information center of the system software modules. The logging system is responsible
for most of the information outputs, and it also makes detailed classification to filter the
information efficiently. Coupled with the debugging program, the information center
provides powerful support for the network administrators and the R&D personnel to
monitor the operating status of networks and diagnose network failures.
The log information format is:
% <priority> timestamp sysname module/level/digest:content
The closing set of angel brackets < >, the space, the forward slash /, and the colon are
all required in the above format, and % is optional.
The format of the log information output to the log host is:
% <189>Jun 7 05:22:03 2006 H3C IFNET/6/UPDOWN:Line protocol on interface
Ethernet0/0/0, changed state to UP
The description of the components of log information is as follows:
1) %
In practical output, some of the information is started with the % character, which
means a logging is necessary.
2) Priority
The priority is computed according to following formula: facility*8+severity-1. The
default value for the facility is 23. The range of severity is 1~8, and the severity will be
introduced in separate section.
Priority is only effective when information is sent to log host. There is no character
between priority and timestamp.
3) Timestamp
If the logging information is send to the log host, the default format of timestamp is date
The date format of timestamp is " Mmm dd hh:mm:ss yyyy".
